MIXING FAUCET.

.application led February 15, 1921.- Serial No. 445,061.

To all whom tf/nay concern.'

Be it known that we, WILLIAM A. ENG- LAND and JOSEPH L. MATTINGLY, citizens of the United States of America, yand residents, respectively, of the city and county of San Francisco, and Berkeley, county of Alameda, State .of California, have invented a new and useful Mixing Faucet, of which the following is a specification.

Our invention relates to faucets and especially to faucets for mixing and delivering two fluids such as a syrup and carbonated water.

One of the objects of our invention is the provision. of a faucet of the character referred to in which dripping of the fluids from the end of the faucet is prevented. An-

other object is the provision of' a faucet' which thoroughly mixes the fluids as they pass through it. Another object is to provide a faucet wherewith the volume and velocity of a discharging stream may be varied without varying the proportions of the component fiuids.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of our invention which is .illustrated in the drawings accompanying and forming part of the specification. It is toy be understood that we do not limit ourselves to the showing made by the said drawings and description, as we may adop-t variations of the preferred form within the scope of our invention as set forth in the claims.

Referring to the drawings:

Fig. 1 is a side elevation of our faucet, showing the same mounted on a panel. Fig. 2 is also a side elevation, but with certain portions removed and the other portions sectioned. Fig. 3 is an elevation of the valve disk. Fi 4 is a Vertical sectional view, the planes ofr section being indicated by the line 4 4 of Fig. 1. Fig. 5 is a horizontal sectional view, the planes of section being indicated by` the line 5 5 of Fig. 1. Figs. 6 and 7 are elevations partly in section, and showing a modified form of faucet.

Our faucet comprises a stationary head 2 mounted on any convenient support'such as thev panel 3 by the bracket 4. The bracket 1s hollow and a coupling 6 on its inner endl provides means for connecting it to the p'ipe 7 through which one of the fluids such as carbonated water is conducted under pres-y sure from any suitable source. site end of the bracket connects with a passage 8 whichopens in the port 9 on the proportional valve seat 10. The valve seat comprises preferably a pieceof leather sunk into the head and prevent lits turning. The other fluid such as a syrup or a flavoring compound, which is to be mixed with the carbonated water is conducted to the head through the The oppopipe l1 in the cupped'v of polygonal form .to ,I

upper end of which, the storage container 12 rests. The pipe 11 connects with a passage 13 in the head which opens in the port 14 on the valve seat.

'Opening on the valve seat in the port 1.6, below the port passage opens in lat- 14, is the passage 17 which extends downwardly through the lower ex-l tension 18 of through the head and opens directzle 28. The nozzle piece is threadedon the an annular space surrounding the cups'` for the passage of the Huids.

A screw 29 acting as a valve is disposed in the extension 18 to control the size of the passage 17, andmay be adjusted to ermit' the desired maximum flow of syrup.l t will be noted that since thea 'valve is adiacentthe lower end ofthe passage it contro s, the

fullest/possible head of syrup is available' for forcing the flow through the passages and proportional valve above thepcups. A plug screw 31 fills the end of the threaded recess in which the valve 29 lies.

lextension 18 and is proportioned to leave 10ovv plate 33, which is provided with a passage .respectively with ports 9 Arranged on .the valveseat 10 is a valve 34 opening on the face of the valve in two ports 3 6 and 37 adapted to be registered and 23. A second passage 38 opens on the face of the valve in ports39 and 40, adapted Lto be re istered respectivelywith ports 14 and 16. llotating the valve plate to cover or uncover these registrable ports, therefore controls the flow of fluids through the passages to the stem and fimpinging of the key 42 pro- .portional at all down the passage l stream,

lower cup thoroughly mingles therewith.

vides means for adjusting the pressure of the valve plate against the valve seat.

@n the'opposite side of the head the hood 52gives symmetry. rllh'e hood is pierced by the pin. 53 which forms a pivotal'mounting for the other arm 54 of the handle. Rotary movement of the handle is limited by the fixed stop 56 on the head and the adjustable pin 57 on the handle. With the handle against the stop, the maximum volume of fluid at the maximum velocity is delivered from the nozzle 28.

Operation: With the valve 29 adjusted to the 'desired flow of syru under the head provided by its own weight, the handle is pulled forward to turn the valve plate. As the valve turns, the ports are alined, the degree of opening of the passages being protimes. rlhe syrup runs 17 into the lowerl cup 22, and the carbonated water discharging under ressure from passage 24 into the upper cup 1s didused and the stream broken up therewhich, striking `the syrup inthe After churning about in the space between the mixed uids 4pass the lower the cups from which the cup and into the nozzle, mixture is discharged.

'llhe proportions of the annular space surrounding the lower cup andof the nozzle discharge opening are carefiill determined to prevent the hacking up o the carbonated water through the syrup passages. Upon shutting od the faucet, Vthe fluids in the 'passages below the valve drain into the cups which retain'them until the faucet is again used. Dripping of the fluids between operations is therefore eliminated.

While the handle will Vbe customarily .movedto fully open the passages, it is to be noted that, a partial opening will not change to emerge past-the cup in an annular Maaate Vfied form of our faucet more desirable for serving certain drinks than thefaucet just described, in that a greater foaminess is imparted to the beverage. lin this structure the tube 61, similar to tube 19 shown in Fig. 4, and having a cup 62 formed on its lower end similar to the cup 22, is threaded into the lower end of the extension 18. The jet nozzle 63, formed by a loop of small caliber pipe, having the open ends secured in the threaded plug 64 is secrewed into its socket formed about the opening of the passage 24. v

rlhe jet nozzle extends into the cup 62 and discharges its fluid from an orifice 66 directly into the mixing cup. The action of the relatively smaller volume of carbonated water at a relatively higher velocity upon nected passages, unitary means for connecting the related passages in each group, means for supplying one of the fluids to be mixed to one end of each group of passages, and means at the other ends of v said passages for mixing said fluids and discharging the mixture- 2. A mixing faucet comprising a head formed with groups of related but unconnected assages, means for simultaneously connecting the related passages in each group for the flow therethrough ofthe. fluids to be mixed in unvaryingl proportions, means for supplying one of said fluids to one end of each group of passages, and means at the other ends of said passa es for mixing said fluids' and discharging t e mixture.

3. A mixing faucet comprising a head, avalve seat yarranged on said head, said head being formed with groups of related passages opening in ports on said valve seat, a valve plate mounted for movement on said valve seat and formed with assages therein for connecting the ports o the related passagesof each group, means for supplying one of the fluids to be mixed tov lll@ assenze p be mixed in unvarying proportions, means for supplying one of said iuids to one end of said group of the other ends of said passages for mixing said fluids and discharging the mixture.

5. A mixing faucet comprising a cup, means for feedingA to said cup one of the fluids to be mixed, means for simultaneously directing a stream of the other fiuid to loe mixed into said cup, and a nozzle for discharging the mixed fluids.

-6. A mixing faucet comprising a cup, means for feeding to said cup one of the iuids to be mixed, means for simultaneously directing an annular stream of the other iluid to be mixed into said cup, and a nozzie Jfor discharging the mixed uids.

7. A mixing faucet comprising a cup, means or feeding to said cup in controllable amounts one of the fluids to be mixed, means controlled by said feeding means for passages, and means at directinga stream of the other Huid to he mixed -under pressure into said cup, and a nozzle for discharging the mixed uids.
